Pressure detection and withdrawal machine for wheel set

The utility model discloses a pressure detection and withdrawal machine for a wheel set. The pressure detection and withdrawal machine comprises a base, a fixed stander device, a pressure head oil cylinder, a detection system, a hydraulic system, an electric control system and a follow workbench, and is characterized in that: the U-shaped fixed stander device is arranged at one end of the base; the pressure head oil cylinder is arranged in the middle of the U shape; clamping claw mechanisms are arranged at two ends of the U shape; clamping claw oil cylinders are arranged on two sides of the U shape; and the follow workbench is arranged on the base. The pressure detection and withdrawal machine performs withdrawal through clamping claws which clamp the wheel set, so that the problem that the conventional pressure detection and withdrawal machine cannot perform withdrawal because the wheel set is close to a case is solved; the pressure detection and withdrawal machine has a simple and rational structure; due to a structural design of the oil cylinders and the follow workbench which is capable of rotating 360 degrees and moving forth and back as well as left and right, all wheels sets with different types home and abroad can be positioned and supported conveniently, quickly and reliably; the follow workbench can bear the weight of over 10 tons; and a withdrawal and pressure detection test requirement on the wheel set of a high-power locomotive with a motor can be met.
